The first day I got my Riva 510, I went from a PAD to three analogs. I continued on exactly that course for another two weeks, until I realized that with just a little push from myself, I could give up my post-dinner analog. I chain vaped at the highest strength I had until the urge passed, and it wasn't fun per se, but it wasn't as hard as I thought it was going to be. That success made me feel so good, that I decided to try to go the next day with no analogs. I failed almost immediately when I had my morning cup of coffee with my boyfriend smoking by the window. BUT the next day, I tried again and succeeded. And now it's been three weeks with no analogs. Sometimes I still want a cigarette, but I just reach for my Riva, and the urge passes after a few minutes. If I do give in, it won't be the end of the world, either. I know that it's just my brain switching habits, and my body wanting that instant fix, as opposed to taking a few minutes for vaping to kick the urge.
I think the trick is to be easy on yourself, but also, give yourself a very small push once in a while. And all the advice about getting the right nic strength and a flavor you like is so true. I spent a few days at 16 mg, before I realized that I was niccing out a little all day long. Your body is going through so many changes at first, that it can be hard to trouble shoot. At one point, I thought my anxiety was from having too much nic, when it was actually caused by too little!
